Discusses the emergence of chaos as a major scientific subject and its place in historical, scientific, and technological context. Three sections provide (1) an overview of the scientific paradigm; (2) a review of the ideology of classical mechanics; and (3) examples of classical systems behaving in peculiar, nonintuitive manners. (MDH)

Presents an experiment to investigate centripetal force and acceleration that utilizes an airplane suspended on a string from a spring balance. Investigates the possibility that lift on the wings of the airplane accounts for the differences between calculated tension and measured tension on the string. (MDH)

Discusses (1) the need for teachers to understand student conceptions; (2) alternative conceptions that students formulate; (3) changing conceptions; (4) representing conceptual knowledge for studying conceptual change; (5) strategies for inducing change; and (6) a taxonomy of conceptual change. (Contains 61 references.) (MDH)

Twelve studies examined implications of age-related changes in movement between 6 weeks and 52 years for various psychological domains. Findings indicate an inverted U-shaped pattern in limb movements per hour that peaked in middle childhood, later than expected. This pattern in motor activity has relevance for development, and for ADHD,…

The study and utilisation of pendulum motion has had immense scientific, cultural, horological, philosophical, and educational impact. The International Pendulum Project (IPP) is a collaborative research effort examining this impact, and demonstrating how historical studies of pendulum motion can assist teachers to improve science education by…

This paper examines the idea that particular representations differentially support and enhance different cognitive processes, in particular different types of reasoning. Five case studies were conducted consisting of detailed observations of pairs of middle-school students interacting with a computer-based learning environment. The software…

This paper reports a 4-month study that investigated the effectiveness of curriculum materials incorporating the history of science (HOS) on learning science, understanding the nature of science (NOS), and students' interest in science. With regards to these objectives, three different class contexts were developed with three main types of…

A gender gap between boys and girls has been reported in computer usage. Graphics may play a role in bridging that gap because of their motivational value. The literature reports gender differences regarding graphic content, color, detail, size, and movement. Based on these findings, preliminary design guidelines for graphics in computer-based…

This practicum addresses the problem of limited interaction between physical therapists and families of developmentally delayed/physically impaired preschool-age children. A program was developed in which the physical therapist was videotaped handling and exercising a child, while explaining the purpose of the movements and instructing the parent…

One area explored in the second (in-depth) phase of the Learning in Science Project was "children's science," defined as views of the world and the meanings for words that children have and bring with them to science lessons. The investigation reported focuses on students' thinking regarding their views on friction. Students (N=47) were…

This teaching guide for motor development in the primary grades describes various areas of concern in motor development and suggests activities for the development of young children in each area. Section I discusses the importance of motor development. The next six sections define and describe particular areas of motor development and suggest…

The papers in this document represent preliminary results of a study which is part of a 3-year project being conducted by the Educational Testing Service in cooperation with the New York City Board of Education, with support from the Carnegie Corporation of New York. This document is divided into seven sections: (1) Introduction, (2)…

Why and how architecture and interior design can stimulate exploratory locomotion is discussed in terms of research and testing into human response. Two kinds of locomotion are defined, exploratory and habitual, with regard to locomotion and behavior responses to the architectural environment. Measuring responses with a hodometer is outlined with…

Describes experiences with turtle graphics to demonstrate motion in a constant gravitational field. Provides the computer program and typical diagrams. (YP)

Introduces two hands-on experiences, related to rotational motion and moment of inertia. Discusses the experimental procedures and provides figure of apparatus. (YP)
